BOYD BYRON BOBB, OF HAYNES, NORTH DAKOTA.

WIRE-STRETCHER.

To all whom it may concern:

Be it known that I, BOYD BYRON BOBB, a citizen of the United States,residing at Haynes, in the county of Adams and State of North Dakota,have invented certain new and useful Improvements in ire-Stretchers, ofwhich the following is a specification.

This invention relates to fence building apparatus, and moreparticularly to wire stretchers, and has for an object to provide such adevice which will be of extremely small size, which will comprise butfew parts, and which will require but one operator to manipulate it andfasten the wires stretched.

A particular object of the device is to provide a novel form of wiretake-up adapted to continuous operation to stretch a wire to any extentdesired, yet without the necessity for a complicated reel.

Another object is to provide a novel method of anchoring the stretcher.

A further object is to provide a stretching lever and fulcrum adapted tocooperate in a novel manner for stretching wire.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimwithout departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure l is a top view of the device secured to a post or engagedtherewith, Fig. 2 is a side view of the wire engaging side of thedevice, Fig. 3 is a rear view of the device.

Referring to the drawings, there is shown a stretcher comprising ananchor member 10 comprising integrally formed right angled arms 11 and12, the arm 12 carrying adjacent its junction with the arm 11 a lug 13having a circular serrated face 1 1 presented toward the junction of thearm and outwardly of which there is an eccentrically pivoted disk 15having its serrated edge disposed toward the lug l3 and carrying anoperating stem 16, as shown. Pivoted upon the arm 12 outwardly of thelug 13, there is an operating lever 17, having a pivot extension 18extending at right angles to the lever,

its outer end being the pivotal point. Adj acent its junction with thepivot portion 18, the lever carries a lug 19 similar to the one 13 andhaving pivoted outwardly thereof an eccentric disk 20 similar to the one15. Each of the disks l5 and 20 are pivoted upon pin members 21 uponwhich are engaged small springs 22 coengaged with the disks to hold thedisks yieldably engaged against the lugs 19 and 13. The inner edges ofthe arms 11 and 12 are provided with teeth 23 for engagement with a postto prevent rotary slipping of the anchor therearound as will besubsequently apparent. Spaced inwardly of the outer end of the arm 12there is a check pin 21 and outwardly of the pin there is pivoted alever 25 carrying a pin 26 adapted for adjustable engagement with achain 27 secured to the outer end of the arm 11. The chain is adaptedfor engagement with a post to retain the anchor thereon, the teeth 23being disposed against the post and the chain 27 carried therearound andengaged over the pin 26, the lever 25 having been previously oscillatedinwardly of the pin 24. The lever 25 is then drawn outwardly to take upthe slack in the chain 27 and upon being brought into contact with thepin 24, the tension of the chain 27 will hold it in locked positionthereagainst.

In operation, the stretcher is engaged with the post as above described,and the wire to be stretched is disposed between the disks 15 and 20 andthe lugs 13 and 19, the disks being removed from engagement with thelugs by means of the operating stems. Continued oscillation of the lever17 will then take up the wire to any extent desired, as will be readilyunderstood.

IVhat is claimed is A wire stretcher comprising in combination, a baseanchor member including integral right angle arms having post-engagingmeans on their inner faces, a lever pivoted upon the anchor member,integral wire-engaging lugs formed upon the anchor member and the lever,pivoted clamping members disposed adjacent said lugs for coengagementtherewith in stretching a wire, a lever pivoted to the outer end of oneof the arms of the anchor, a check pin carried by the arm inwardly ofthe lever for checking engagement therewith, a pin carried by the leverinwardly of its plvot point, and a chain carried by the outer end of theoppo- In testimony whereof I aflix my signature, site arm and adaptedfor adjustgblle engagein presence of tWo Witnesses.
